Recently at the SXSW Interactive conference in Austin, Texas, Instagram, a photo-sharing application that has taken a lead on iOS, revealed that it has passed 27 million registered users. Although Kevin Systrom, Co-founder, didn’t disclose the number of daily activations, but said that out of all the users who have been active in the last week, 67 percent have also used the application the day prior to the announcement.

Systrom also showed off the company’s upcoming Android application. Although he didn’t give a full demo of the application he just waved it around very briefly. He also added that this Android application is better than their iOS application.

Apart from that Co-founder Mike Krieger also added that folks from Android are impressed with the way the application leverages the platform. Systrom also mentioned that they have been busy with their scaling on iOS, so it took a while for them to come to Android. He also believes that it was also not very late and if they would have tried to work on both at the same time the innovation they have come up with would not have been possible.

The application doesn’t have any advertising till now and it doesn’t have any in-application purchases. Systrom also believes that Instagram has put a stake in the ground and they are growing faster than anyone.

Although they launched in the fall of 2010 but was not very successful in that sense. But later the application was able to secure the top position among photography applications and consistently maintained its high rank on the free application charts. Months later the company even managed to pick up a $7 million Series.
